OIL-LAMP.

SPECIFICATION forming part of Letters Patent N 0. 684,636, dated October15, 1901. Application filed November 24, 1900. Serial No. 37,601. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, JULIO GUIMARAEs, a citizen of Argentina, residing inBerlin, Germany, have invented certain new and useful Improvements inOil-Lamps, of which the following is a specification.

This invention relates to improvements in petroleum or other oil lamps;and the object of the invention is to improve the construction of suchlamp so that a powerful white flame, similar to that produced by anincandescent burner, is obtained, however, without the use of anincandescing mantle.

For this purpose the invention consists in the combination of anoil-reservoir having a conical bottom, a hollow foot supporting saidbottom, and having two series of openings for admitting air thereto, adraft-tube extending upwardly from the upper open end of said conicalbottom, a flame-deflector supported above the draft-tube, a burner-bodysupported on the oil-reservoir and provided with perforations, a gallerysupported on the burner-body, a cap supported on the burner and adaptedto cover the lower blue portion of the flame, a globe supported on thegallery, said gallery having perforations for admitting air into theglobe above the cap, a chimney', and a ring secured to said chimney andresting upon said globe, the lower end of said chimney being flared andlocated above said flame-deflector and cap, and said ring being providedwith perforations for admitting air into the top of the globe.

The accompanying drawing illustrates, partly in elevation and partly insection, a lamp constructed according to my invention.

The lamp shown comprises an oil-reservoir 1 a, which has a conicalbottom b, which is supported by a foot 0 of the lamp. From the smallerupper end of the conical bottom Z2 extends in upward direction adraft-tube d, which serves not only as a draft-tube, but also as aninterior guide for the wick. Upon the perforated shell e of the burneris located the gallery f, and upon the latter is supported the globe g,preferably made of glass. The chimney 7t passes through the opening atthe top of the globe g and is supported centrally in the globe by meansof a perforated ring i, which is frictionally or otherwise secured tothe chimney 7t and rests upon the globe g, or the chimney may besupported by any other suitable means upon the globe g, so that itslower end is located above the flame-deflector, cap 25, and draft-tube.The capi is supported on the burner and extends upward in such a manneras to cover the lower blue portion of the flame l, (indicated by dottedlines,) so that the same is not exposed to view. The chimney 7c ispreferably provided at its lower end with a flaring rim, as shown, so asto receive the flame and draw the same into the chimney after it hasbeen deflected outwardly by the flame-deflector.

The flame Z receives a supply of air from four diderent sources, first,through the openings at and 0 in the foot of the lamp; second, throughthe openings to in the body e of the burner; third, through theopeningsp in the bottom of the burner-galleryf, and, fourth, through theopenings q in the ring '5 at the top of the lamp-globe. By thearrangement of these openings and the conical form of the bottom I) ofthe oil-receptacle an extremely powerful draft of air is insured. Theair entering at m and 0 is compressed, owing to the conical form of thebottom of the oil-reservoir, and is carried upward through thedraft-tube (Z. By the air entering the openings 19 and g, which arearranged opposite one another, respectively, below and above the frame,counterdrafts are created in the globe, which, on the one hand, serve tocool the globe, which is necessary, owing to the great heat of theflame, and,on the other hand, serve to supply the flame above the captwith the large amount of air which is necessary for perfect combustion.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In an oil-lamp, the combination of an oilreservoirhaving a conical bottom, a hollow foot supporting said reservoir andhaving two series of openings for admitting air below the conicalbottom, a draft-tube extending upwardly from the upper open end of saidconical bottom, a flame-deflector supported above the draft-tube, aburner-body supported on the oil-reservoir and provided with a gallerysupported on the perforations,

10 provided with perforations for admitting air into the top of theglobe, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
